The main objective of this study is to establish an appropriate method for the
characterization of the pigments, materials and structure of the paint layers in a copy of the …

This work presents a spectral color-imaging procedure for the detailed colorimetric study of
real artworks under arbitrary illuminants. The results demonstrate this approach to be a …

This study aims to compare different hyperspectral imaging devices and identify their
suitability for in-situ color and lighting research. Three hyperspectral cameras were …

In the cultural heritage preservation of medieval buildings, it is common to find plaster walls
covered in lime, which previously were painted in polychromy. The conservation …

Commercial hyperspectral imaging systems typically use CCD or CMOS sensors. These
types of sensors have a limited dynamic range and non-linear response. This means that …

This paper outlines the use of bidirectional reflectance measurements for the
characterisation and evaluation of appearance changes in gilded surfaces caused by …

Color reintegration is a restoration treatment that involves applying paint or colored plaster
to an object of cultural heritage to facilitate its perception and understanding. This study …

Materials with complex optical properties like gold foils are commonly used for gilding in the
field of conservation and restoration to render the visual appearance of the restoration …

Lamps that produce light as a result of electrical current through a metal wire, contained in a
small transparent bulb that heats the metal to incandescence. The bulb also contains …

RGBN multispectral filter array provides a cost-effective and one-shot acquisition solution to
capture well-aligned RGB and near-infrared (NIR) images which are useful for various …
